Editor crashes to reference that does not exist

Hi,

If I’m reading this error correctly its saying there’s a problem with a widget inside one of my widgets. I’m pretty sure I added a tree and then deleted it later, really don’t know what to do here, the engine crashes pretty much every other time I run the game in viewport.
